The search facility is a little idiosyncratic, but it does work. At the top of the page you'll see a box which says Search this site. If you click on the magnifying glass to the right of it, it will bring up another Search box where you can type the subject you want to search for.
But don't worry about asking questions that have been asked before - we don't mind answering and if we remember there's been a thread about it we can post a link for you - if we can find it
